System And Method For Selective Estimation Of Battery State With Reference To Persistence Of Excitation And Current Magnitude

A system for monitoring a battery comprising:

• a sensor configured to identify a level of electrical current that is supplied to the battery;
• and
• a controller operatively connected to the sensor and configured to:
• identify a persistence of excitation in a battery;
• identify an average magnitude of the electrical current that is supplied to the battery with reference to at least one electrical current level identified by the sensor;
• and
• perform a state estimation process for the battery only in response to the identified persistence of excitation exceeding a first predetermined threshold and the identified average magnitude of the electrical current exceeding a second predetermined threshold.
